There are numerous experiments that show in a tangible way how sound has the ability to sort and harmonize matter. Ernst Chladni, German scientist of the s. XVII, known as the father of acoustics, impressed the French scientists and Napoleon himself in 1809. To prove his thesis that the vibrations of sound could move matter, he threw the sand into a plate placed on a pedestal and then passed a violin bow from the edge of the plate. Immediately the sand gathered together forming beautiful geometric shapes, similar to a mandala.
Since then there have been many demonstrations in the scientific field of the ability of sound to order matter.
Already in the 20th century, a Swiss scientist, Dr. Hans Jenny, was able to influence this quality of sound in images. In his experiments, called bugs, he often applied sound waves on a sheet of metal on which he deposited a very fine sand called lycopodium. The result was exquisite kaleidoscopic compositions, some of which reproduce natural forms, such as snowflakes, flowers and spirals.
These are some examples of the experiments:
